Beit known that I, CHARLES R. GREUTER, a citizen of the United States, residing at Holyoke, in the county of Hampden and State and useful Improvements in Feed Mechanism for Gasolene or Like Engines, of which the following is a speciication.

My invention pertains to that class of enor enriched by admixture therewith of the vapor of a suitable hydrocarbon to produce an explosive mixture; and it consists in what may be appropriately termed a measuring valve mechanism, whereby the quantity of hydrocarbon admitted at each movement of the piston, cam, or other actuating device may be nicely regulated and controlled.

The invention is susceptible of varied emin the accompanying drawings.

The invention will be explained in connection with the accompanying drawings, in whichh Figure lis a vertical sectional view through the air-intake of a gasolene or like engine, showing the valve controlling the same and also showing in section the casing of the valve to which the present invention particularly and mechanism; Fig. 2, a similar view of the oil or hydrocarbon valve, showing the latter in its elevated position; and Fig. 3, ahorizontal section on the line 3 3 of Fig. l.

The apparatus here shown is preferably made as an attachment for engines generally of the class mentioned and is designed to be bolted or otherwise secured thereto at such point as the design ofthe engine shall require v 4o or render expedient; but it may be made as an integral part of the engine, if preferred, in which case its shell or casing may be cast integral with the cylinder or jacket of the engine.

Referring to Fig. 1, A indicates a hollow Serial No. 712,445. (No model.)

ber, as desired. The valve shell or chamber b is formed with an annular valve-seat CZ, upon which normally rests a valve B, the stem e of which is guidedin a neckf, extending downward from the shell or chamber b. The stem e protrudes from the neckf, and its exposed end is screw-threaded to receive a nut g and jam -nut h, the former being formed with an annular ledge or shoulder/i to support a Vspiral spring C, which encircles the stem e and neck f. By adjusting the nut g the compression of spring C may be varied, and by means of jam-nut 7L the nut g can be held against accidental turning. Stem e may be lifted periodically by a cam D or by a lever or other common means.

The office of valve B is to control the admission of air and vapor into the combustionchamber or into a preliminary mixing-chamber, as above indicated.

E indicates a lever fulcrumed at one end in or upon a lug or stud j, projecting inwardly froml the shell or casing A or from a head or cap k, detachably secured thereto. The free or swinging end of lever E is forked to straddle the stem e of valve B, and the arms of the forkare slotted to receive a pin Z, which passes through the stem and projects on opposite sides thereof. By reason of this connection of the lever E with the valve B or its stern e it follows that when the valve rises or falls the lever must do the same.

Rising from the intake pipe or branch of the shell A, but conveniently made as a separate part and attached thereto, is a secondary shell or casing F, in which is arranged the valve G, by which the delivery of oil or hydrocarbon is controlled.

Shell or casing F is considerably larger in diameter than is the valve G, and within it is placed a plug H, here represented as of cylindrical cross-section, but which may be of any form which may be given the shell F.

Shell or casing F is provided with a lateral arm or branch m, which is bored toform an inlet-passage n for oil or hydrocarbon. Said branch will in practice be connected with a suitable reservoir or supply-tank containing oil or hydrocarbon.

Opposite or at the height of the inner end IOO of the passage n the plug H is provided with a circumferential groove or channel o, of vertical measurement greater than the diameter of passage n, so that it may communicate with said passage even though raised or lowered somewhat from its normal position.

Valve G is formed or furnished with a stem p, which passes axially through the plug H and out through the top or head of shell F and also extends downward through the bottom of said shell and rests upon a boss q, formed upon the lever E. Said valve is formed with two faces, one above and the other below, each beveled or made conical to fit a seat of like form. The lower seat for valve G is formed in the bottom of shell F, while the upper seat is formed in the lower end of plug H.

The opening surrounding stem p of valve G is made somewhat larger than the stem from the upper side of the valve to a point somewhat above, and the same is true of the opening through which the portion of the stem beneath the valve passes, the purpose being to form a space or passage for oil or hydrocarbon. The space r thus formed above valve G communicates by holes or passages s with the circumferential channel o of the plug H, and hence with the inlet-passage fn.

The stem p of valve G has at a point above the upper end of plug H a horizontal enlargement or disk t, above which is placed a spring u, whicl1,bearing upon the disk at one end and upon the head or cap of shell F at the other end, tends to hold the valve G to its lower seat. Beneath the disk or enlargement t is asecond spring fv, of larger diameter than spring u, or otherwise adapted to yield somewhat more readily by preference, said second spring tending to press the plug H downward toward the lower end of shell F, yet permitting it to be raised or lowered without affectp ing the position of valve G or its stem.

Plug H is or may be raised from its seat upon the lower end of shell F bya rod or stem w, screwed or otherwise made fast thereto, extending upward loosely or freely through thetop or head of shell F and provided with a nut .7c and jam-nut y, by which the rod or stem, and consequently plug H, may be raised to and held at any desired elevation.

When plug H is raised, a space ct is left between its lower end and the bottom of shell F, as seen in Fig. 2, which space, being above the lower valve-seat, receives oil or hydrocarbon through the passages s when Valve G is upon its lower seat and which may escape from said space when the valve is lifted. The space is always of relatively small capacity and of quite limited height, or, in other words, the plug is lifted but a short distance therefrom at any time, and the valve in moving upward so quickly reaches its upper seat and cuts off communication with passages s that no appreciable addition can be made to the quantity contained in said space until the valve again descends. The space beneath the plug H is vented by a tube or passage ,a to insure the free delivery or discharge of the oil or hydrocarbon therefrom.

I indicates a cone-shaped spreader located beneath the passage through which the oil or hydrocarbon descends from the space beneath the plug H.

The apparatus being thus constructed and suitably applied to and connected with an engine of any appropriate type, its operation is as follows: At each recurrence of the period for charging the mixing-chamber or the combustion or explosion chamber, as the case may be, the valve B is lifted from its seat and the suction or vacuum within such chamber causes air to rush into and through pipe or nozzle a and thence to said chamber. same time and by the same act lever E is elevated, and with it the stem of valve G and said valve itself, as seen in Fig. 2, thus freeing the oil or hydrocarbon in the space beneath plug H, which oil or hydrocarbon, falling upon cone or spreader I, is broken up or divided into small particles or globules, which are taken up either as such or as vapor and carried along by the air-current. By adjusting the plug higher or lower the capacity of the oil-space may be increased or diminished at will; but ,when the adjustment is effected the feed will continue uniform until the adjustment is changed.

The device is simple in construction and efficient in action, insuring a regular and unvarying supply of oil or hydrocarbon and consequent uniformity of action of the engine.

vBy the use of this device it is practicable, with proper variation of adjustment, if any be needed, to use or to adapt the apparatus for supplying at will gasolene or like volatile hydrocarbon or kerosene or other less volatile fiuid.

As above suggested, the details may be varied considerably within the scope of my in-l vention. Thus, for instance, the oil-space may be Vented by an opening directly through the plug H, the plug may be adjusted by other means, the form of the valve may be modified, and like modifications may be made.

Where the device is to be employed always with a given oil or carbureting fluid, it will be found practicable merely to form grooves or channels in the plug of determinate capacity, in which case no provision for adjustment of the plug need be made. It will be found advisable, however, to provide for the rise of the plug when encountered by the valve G in its upward movement to guard against injury through overthrow of the lifting device should such occur.

Having thus described my invention, what I claim is-n l. In combination with a hydrocarbon-engine, a reservoir for hydrocarbon; a valve shell or casing interposed between the engine and the reservoir; a plug adjustable within said shell; oil-ducts leading from-the reservoir to the base of the valve-shell; and a valve arranged Within said shell and adapted to seat At the IOO IIO

alternately against the bottom of the shell and against the lower end of the plug.

2. In combination with a hydrocarbon-engine, a shell or casing provided with an inlet for hydrocarbon, and an outlet therefor; a valve-seat encircling said outlet; a plug within said casing also provided with a valve-seat; means for adjusting the plug relatively to the valve-seat of the shell and preventing nearer approach thereto; a valve interposed between the two seats and adapted to rest alternately upon them; and means for moving the valve from one seat to the other.

3. In combination with shell F having an inlet for hydrocarbon, and an outlet therefor; plug H arranged within said shell and provided with oil-passages; valve G adapted to seat alternately against the bottom of the shell and to close the outlet thereof, and to seat against the end of plug H and close its oil-passages; springs serving to press the valve to its seat and to urge the plug toward the bottom of the shell; and means for elevating the valve G.

4. In combination with intake-valve B, le-

ver E; shell or casing F; plug H Within said casing; oil-ducts leading to the base of casing F; valve G adapted to seat alternately against the lower end of plug H and the bottom of theshell; springs fu and u serving to press the plug and the valve respectively to their seats; and rod or stem w provided with a nut, for adjusting the plug within the shell or casing.
